I bought 2 pairs of water shoes from this seller. The two pairs have completely different materials of construction. The Velcro pair turned into a messy, sodden fabric. The insole was mainly made of sponge. Wearing on sand or gravel bottom is terrible. In my opinion, it should not be used for external use. I would return them but have used them on Lake Michigan. Put them in the direct sun for 12 hours and they still won't dry out. The insole is so thin that it doesn't stay in place. Just remember that different colors are completely different. My first pair was grey/gold with a clear sole. You are beautiful.
